DUMPINGLCAR.

SPECIFICATION forming part of Letters Patent No. 290,298, dated December1S, 1883.

' Application led September 2B, 1883. (No model.)

.T0 all wiz/0m it may concern:

Be it known that I, GEORGE J. WHEELocK, a citizen of the United States,residing at Oakland, Alameda county, State of California, have inventeda new and Improved Dump-Car, of which the following is a specication.

My invention relates to -those ears used in mining, grading, and forgeneral excavating purposes, which are required to tip over the box orbody, independent of the truck to which the wheels are attached, in theact of discharging the load. .Y

It consists in the combination of machinery by which the dumping iseffected, the object being to keep the height of the car within thelimit required by the truck-frame and car-body, and not occupy-any ofthe height with the dumping machinery-a desideratum in cases where thecar has to enter low-roofed tunnels-and also to obtainasimple, cheap,and effective device for 'the purpose intended.

In the accompanying drawings, Figure 1 is an end view, and Fig. 2 is aside elevation, of my invention.

In both gures like letters of reference refer to like parts.

A is the ear-box, made in ordinary fashion. B is the swinging door atthe dumping side, which is fastened with the cross-bar C. This bar Cswings on a pivot at D, and each end passes into the latches E, whichare fastened on the frame-posts F. The ordinary guides for the bar arefastened on the door itself.

Gr is the truck-frame.

H are the wheels, which turn upon their respective axles, the axlesbeing rigidly held in boxes secured on the under sideof the truck.

I I are rollers, which are provided with short axles which turn insuitable metal boxes properly secured in position upon the truckframe,as shown. Upon these rollers the dumping side of the car-body rests, theopposite side resting squarely on the truck-frame, the blocks T beinginterposed.

J J are toothed racks, which are fastened to the car-bodyunderneath ateach end. With these racks there engage two cam shaped toothedquadrants, K K. The quadrants are secured in proper position upon thesquare shaft L, which runs the entire length of the truck-frame, abouttwo inches to one side of the center line, or four inches nearer thedumping side than the opposite side.- This square shaft is supported inboxes M on the truck-frame, and has two hand-levers, N N, which serve toturn it in operating to dump and return the car-box to its normalposition.

O is a chain, which connects the car-box with the truck-frame. Itsoflice is to prevent the car-box from .being inclined in dumping theload to a greater distance than the length of this chain will permit.

l? P are fiat bars attached to underneath the box of the oar, andresting on each of the three rollers. At a proper point each bar yisprovided with a hook-shaped stop, Q, which, when the car-box is movedsufficiently far sidewise to be in a position to dump the load, the stopstrikes against the rollers and prevents further movement, except in thematter of tipping the car-box over.

The door of the car is suspended on bolts at R.

The car needs no locking device to prevent tipping over or movingsidewise when in transit, for inasmuch as the whole body rests fairly onthe broad support ofthe truck-frame .and the rollers, there is notendency to tip over, and before any side movement is possible thecar-box, with its load, must be actually lifted to enable it to berolled on the rollers.

The operation is simple and as follows: The door is closed and made fastwhen the car is loaded. Afterward, when the car is rolled to itsdumping-place, the door-fastening is swung out, to allow the door toopen, when the operator, at one or the other end of the car, throws overthe hand-lever, which, through the connected machinery, effects thedumping by lirst raising the car-bodyl just enough to cause the wholeWeight to come on the rollers and the quadrants, and to lift the woodenstop-blocks T above the truck-frame,

and then rolling the car-body over until it loses its balance and tipsover to spill out the contents. The chain will cheek the carl bars P,having east upon them the hookzo body from attaining such a positionas'to fall shaped stops Q, which lit the periphery of the off from thetruck-frame entirely. rollers, so that the oar may be tilted Wit-h theWhat I Claim as my invention, and desire smooth :L-Xles of the rollersfor an axis, sub- 5 to secure by Letters Patent, is as follows: lstantially as and for the purpose described. 1.
